There are eight episodes, which relate to the stops on Dippy's journey. Each considers a different theme with clear links to the national curriculum for 7- to 11-year-olds across England, Wales, Scotland and Northern Ireland.

The resources can be used individually and in any order.

Each challenge begins with a postcard from an expert scientist, curator or researcher. At the end of each episode pupils can email their findings to Dippy's team, and will receive a reply.
